I acquired a q-bert cocktail that was mussing it's 13" monitor. I have. 17" wells d9100 that in found will fit in the cabinet however the 9100 is vga input only.
I know q-bert is positive sync so I changed the 7407 at j14 to make the sync negitve then ran both of them together and wired them up to a gonbes 9200 vga converter. Hooked up th vga monitor and I have a picture but it won't lock reliable. It will jump around about every 15 sec in random directions.
Has anyone successfully used a vga converter with qbert weather it be in a cab or bench testing setup?
